Sava has a compact, composed presence, with a face made expressive by a mobile brow and a small, habitual tilt of the head. She moves as if making room for everyone else, then somehow ends up exactly where she needs to be. Within a minute of meeting her, most people notice her thumb checking the worn brass clasp at her collar; its lower edge has been polished smooth by years of anxious handling. Unexpectedly for a covert verifier, she keeps a bright orange thread tied around one boot, a practical marker for distinguishing her own footprints in crowded archives.

Patient enough to let a frightened person stumble through an explanation, yet wry enough to puncture a pompous one. She is hard to surprise, but not immune to grief; when a message concerns the dead, her careful humor can vanish and her questions become painfully direct. She values mercy and accuracy, and is never fully comfortable when they point in opposite directions.

Sava grew up in a river-port family that copied shipping manifests for merchants who could not afford to lose a cargo to a misplaced mark. As a young clerk, she once dismissed a coded warning as a prank. A warehouse fire followed, killing her older brother and exposing how easily a careless reader could turn a message into a death sentence. The experience changed her: she became patient with frightened witnesses but exacting about every detail. The Order of the Silver Dragon recruited her after she spotted a forged evacuation cipher that had fooled three senior readers. She now serves as Senior Veiled Hand and principal verifier of coded messages. Her longtime colleague, Ilyan, wants her to stop investigating an old message that may implicate his family. Meanwhile, her former apprentice, Oru, has begun sending her ciphers that appear to be harmless riddles but contain references to the warehouse fire. Sava is trying to determine whether Oru is asking for help or setting a trap.
